Embodiment Construction

[0012] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] by Figure 1 to Figure 6 Given that the present invention includes the hand 1, the wrist 2 and the forearm 3, the three parts can be assembled together to form an arm model; the arm model is provided with a main fluid channel 4, and both the forearm 3 and the hand 1 There is a liquid return channel 5, and the inner circumference of the wrist 2 is provided with a plurality of rubber tubes 6 with different tube diameters. The wrist 2 can be rotated so that different rubber tubes 6 can be connected to the liquid return channel 5. Connect to the branch liquid channel 7 of the return liquid channel 5 in parallel with the rubber tube 6; the left end of the hand 1 is equipped with a first fixing plate 8, the right end of the forearm 3 is equipped with a second fixing plate 9 and both ends of the wrist 2 A third fixing plate 10 is ins...

Abstract

The invention relates to an intravenous injection simulated teaching device, which effectively solves the problem that the existing venipuncture model is single in function and high in use cost. The technical scheme is as follows: the intravenous injection simulated teaching device comprises an arm model composed of a hand part, a wrist part and a forearm part, wherein a main liquid channel and liquid return channels are arranged in the arm model, a plurality of rubber hoses and a branch liquid channel are arranged in the wrist part, the wrist part can rotate so that different rubber hoses canbe connected in the liquid return channels, two ends of the rubber hoses are provided with communicating devices realizing pipe connecting with the liquid return channels, and the communicating devices can adjust the flow of the branch liquid channel according to the diameters of the rubber hoses. For the intravenous injection simulated teaching device, the whole operation process and various conditions of intravenous injection puncturing are simulated comprehensively and vividly, so that a practicer can perform comprehensive practice, then the proficiency and coping capacity during clinicalpuncture are improved, meanwhile, the rubber hoses can be independently replaced, thus the operation is extremely simple and convenient, recycling can be realized, and the practicer can obtain sufficient practice while the cost is greatly reduced.

Description

Technical field [0001] The invention relates to the field of medical teaching, in particular to an intravenous injection simulation teaching device. Background technique [0002] Intravenous injection is very common in medical work. It is a medical method in which liquid substances such as blood, medicinal solution or nutrient solution are directly injected into the vein. It can directly enter the blood and reach the whole body through the blood circulation. It is the most effective medication. treatment. Medical staff need to master the muscles and vein injections proficiently and need to do a lot of exercises. It is often practiced to practice needles between practitioners. This has great limitations. The practitioners are more painful and cannot practice a lot; although there are intravenous injection models, However, the function is relatively simple and cannot fully simulate various situations of clinical intravenous injection, such as blood vessel thickness, depth, blood p...
